[Elecraft] Fuses in power cable

[Don Wilhelm]

  Matt,

You are correct, there is a resettable fuse for the non-KPA3 power.  And 
those resettable fuses operate quickly.  Still a fuse near the power 
supply is a good idea to protect the wire - but if the power supply has 
current limiting, and that current limit is reasonable for the wire 
size, a fuse may not be necessary.  Like everything else -- it all depends.
